ATRT-1700 Automated Traffic Recorder Tester
The ATRT-1700 is an automated tester of counters and classifiers used in today's traffic industry.  The tester is designed to simulate any type of highway vehicle passing over a user-defined array of highway traffic sensors.  The input sensors available on the ATRT include:  Piezo Strips, Air Tubes, Tape Switches, or Loops.  The tester's software provides the user to select and group vehicles to be generated by the outputs of the tester.  When a test is completed, the data can be compared to the classifier's report for possible variances that may have occurred.

ATRT-1150 Automated Traffic Recorder Tester
The ATRT-1150 is an automated tester capable of testing Road Tube Axle sensors on counters and classifiers used in today's traffic industry.  The counter/classifier under test must be able to count multiple axle vehicles that pass over Road Tube sensor arrays and allow the user to determine the counter/classifier count for the test period.  The user also has the ability to control the level of the output signal being sent to the counter/classifier. When a test is completed, the data can be compared to the classifier's report for possible variances that may have occurred.
